Most advertisers focus on bid amounts when trying to improve ad placement or reduce cost per click. Bids matter. But they are only half of the equation.
Google Ads Quality Score plays an equally important role in determining where your ads appear and what you pay for each click. A higher Quality Score can put your ad above a competitor’s at a lower cost. A lower Quality Score forces higher bids to hold the same position, spending more for the same or worse results.
Understanding how Quality Score works is one of the faster ways to find cost inefficiency in a pay-per-click (PPC) account. A PPC ads agency will review Quality Score as part of any account assessment. Here is what it measures, why it matters, and how to improve it.
What Google Ads Quality Score is
Google Ads Quality Score is a rating from 1 to 10 assigned to each keyword in an account. It reflects how relevant and useful Google considers the ad experience associated with that keyword to be for a searcher.
Quality Score does not determine ad position on its own. It combines with bid amount to calculate Ad Rank, which is the value Google uses to determine where an ad appears in search results and what the advertiser pays per click. A keyword with a Quality Score of 8 and a moderate bid can outrank a keyword with a Quality Score of 4 and a significantly higher bid.
Quality Score is best understood as a diagnostic signal. It tells you how well the ad experience aligns with what the searcher expects. The goal is not to chase a high score for its own sake. The goal is to use the score to identify where relevance is breaking down and fix it.
The three components of Google Ads Quality Score
Quality Score is calculated from three components. Each is rated as above average, average, or below average. These ratings identify where the problem is, not just that a problem exists.
Expected click-through rate is Google’s prediction of how likely the ad is to be clicked when shown for a given keyword. This prediction is based on historical performance data. An ad that consistently earns clicks relative to how often it is shown builds a stronger expected click-through rate over time. An ad that appears frequently but rarely earns clicks signals poor relevance.
Ad relevance measures how closely the ad copy matches the intent behind the keyword being searched. An ad that directly addresses what the searcher is looking for scores higher than a generic ad served across a loosely grouped keyword set. Broad ad groups with loosely related keywords are the most common cause of low ad relevance scores.
Landing page experience measures how relevant, useful, and navigable the destination page is for someone who clicked the ad. Content relevance, page load speed, and clarity of next steps all contribute to this rating. A strong ad pointing to a weak or mismatched landing page will still produce a low Quality Score regardless of how well the ad itself performs.
All three components need to work together. A weakness in any one of them pulls the overall score down.
In practice: A common pattern in account audits is an ad group built around a general keyword like “PPC management” that also serves more specific searches like “PPC management for ecommerce” or “PPC agency for small business.” The single ad cannot speak directly to all three intents, so ad relevance scores average or below for most of them. Splitting that ad group into tighter, intent-matched clusters each with its own ad copy typically lifts relevance scores within a few weeks.
Why Google Ads Quality Score affects what you pay
Ad Rank is the value Google calculates to determine ad position and cost per click. It combines bid amount and Quality Score, along with several other contextual factors. Quality Score is a meaningful input in that calculation.
A higher Quality Score lowers the cost per click needed to maintain a given position. Two advertisers targeting the same keyword can pay significantly different amounts per click based on relevance alone. The advertiser with the more relevant ad experience pays less for comparable or better placement.
A low Quality Score forces higher bids to compete for the same positions. The cost per click rises without any improvement in the quality of traffic being driven. That pattern compounds over time, particularly on high-spend keywords where the inefficiency adds up quickly.
A Quality Score below 5 on an important keyword is a signal that the ad experience is not aligned with what the searcher expects. The cost impact of leaving that unaddressed is real. Start by pulling the component ratings for that keyword — the below-average rating points directly to whether the problem is the ad copy, the keyword grouping, or the landing page. Fix the component that is rated below average first, then reassess after four to six weeks. A digital marketing audit identifies which keywords, ad groups, and landing pages are driving up costs through poor relevance, and gives you a clear starting point for fixing them.
How to improve your Google Ads Quality Score
Quality Score improvements come from improving the three components that determine it. These are the most effective starting points.
Tighten keyword to ad copy alignment. Each ad group should contain closely related keywords, with ad copy that directly reflects those keywords. Consolidating broad ad groups into tighter, more focused ones is one of the fastest ways to improve ad relevance scores.
Write ad copy that matches search intent. The ad should speak directly to what the searcher is looking for at the moment they search. A generic description of the business serves the advertiser, not the searcher. Ad copy that addresses a specific need earns more clicks and builds a stronger expected click-through rate over time.
Improve landing page relevance. The page the ad points to should deliver exactly what the ad promises. If the ad promotes a specific service, the landing page should be about that service. Sending traffic to a homepage or a loosely related page creates a landing page experience mismatch that Quality Score will reflect.
Improve landing page load speed. A slow page creates a poor experience regardless of how relevant the content is. Page speed is a direct input into landing page experience ratings.
Use negative keywords consistently. Ads shown for irrelevant searches produce low click-through rates. Those low rates drag down expected click-through rate scores over time. A well-maintained negative keyword list filters out searches that will never convert and protects click-through rate performance.
Review search term reports regularly. The actual searches triggering your ads reveal mismatches between keyword intent and ad relevance that are not visible in the keyword list alone. Reviewing this report monthly surfaces problems before they compound.
Quality Score changes take time to register. Allow four to six weeks after making changes before evaluating impact.
What a low Quality Score is telling you
A Quality Score below 5 on a keyword that receives meaningful spend is worth investigating. The component ratings point directly to where the problem is.
A below-average expected click-through rate suggests the ad copy is not compelling or not relevant enough to the keyword. The ad is appearing but not earning clicks at the rate Google would expect.
A below-average ad relevance score suggests the keyword and the ad copy are not closely aligned. This is most often a sign of an overly broad ad group where the ad cannot speak specifically to every keyword it is serving.
A below-average landing page experience score suggests the destination page does not match what the ad promises, loads too slowly, or does not give the visitor a clear next step after arriving.

Frequently asked questions about Google Ads Quality Score
These are the most common questions business owners and in-house marketers ask about Google Ads Quality Score.
What is a good Quality Score in Google Ads?
Scores of 7 and above are generally considered strong. They indicate that the ad experience is well aligned with what the searcher expects and that the account is not paying a relevance penalty on those keywords. Scores of 5 and 6 are average and worth monitoring, particularly if they appear on high-spend keywords. Scores below 5 signal a relevance problem that is worth addressing. The lower the score on a keyword with meaningful spend, the more that keyword is likely costing more per click than it should.
Does Quality Score directly affect ad position?
Quality Score does not determine ad position on its own. It combines with bid amount to calculate Ad Rank, which determines where an ad appears and what the advertiser pays per click. A higher Quality Score can achieve better placement at a lower bid than a competitor with a lower Quality Score and a higher bid. This means relevance and bid strategy work together. Improving Quality Score without adjusting bids can still produce meaningful improvements in placement and cost efficiency.
How often does Google update Quality Score?
Quality Score is updated continuously as Google collects more data on how ads perform for a given keyword. It is not a static number. Changes to ad copy, landing pages, or keyword groupings will eventually be reflected in the score, but the update is not immediate. Allow four to six weeks after making changes before drawing conclusions about whether the adjustments have had an impact. Scores on newer keywords with limited data may also fluctuate more than scores on established keywords with a longer performance history.
Can a high bid compensate for a low Quality Score?
A higher bid can partially offset a low Quality Score in terms of Ad Rank and position. But the cost inefficiency remains. Paying more per click to maintain a position that a more relevant ad would hold at a lower cost is not a sustainable approach. It increases spend without improving the quality of the traffic being driven or the relevance of the experience for the searcher. Fixing the underlying Quality Score problem produces better results than bidding around it.
Key Takeaways
– Google Ads Quality Score is a 1 to 10 rating that reflects how relevant and useful the ad experience is for a given keyword. It combines with bid amount to determine ad position and cost per click.
– The three components are expected click-through rate, ad relevance, and landing page experience. Each is rated above average, average, or below average, pointing directly to where the problem is.
– A low Quality Score on a high-spend keyword costs more per click than it should. When a component rating is below average, fix that component first rather than bidding around the problem.
– Improvements to ad copy, keyword grouping, and landing page relevance take four to six weeks to reflect in Quality Score. Make changes systematically and measure after giving them time to register.
